What you call improvements is just a complication of the game, I don't have a daily win now, the fish has become solitary, there is almost no benefit from it, new lives from friends come very rarely, although there are a lot of friends on the list, my sister plays almost at the same level, but she has all that I have lost plus various additional features like add moves, boosters, etc.
I understand that you are interested in making the game as difficult as possible so that people buy boosters, but it is unclear why there are additional features for some, and not for others. In the end, you can show ads to those who do not want to pay real money.
I am now at levels over 17,000, episodes at these levels contain 10-12 difficult and super difficult levels, without boosters it is almost impossible to fight to win an episode and get gold, it is a pity that I have to leave the game, but you made me do it, good bye
